I just heard that you cannot drag a message directly to your personal folders. Those messages will not be reconciled with the BlackBerry, only messages that are moved within your exchange mailbox will be reconciled.

As long as you are filing items into folders that are located within your exchange mailbox (.OST) and not to personal folders (.PST) incoming mail that you file in those folders will reconcile properly (sometime, it takes a couples of minutes) to the BB device.

Would be nice though to have BES and outlook also consider items that leave my outlook inbox and are filed to my personal folders.

I guess it needs just an intermediate step of filing from my inbox to any .OST folder (so that the BB knows it is gone from my mail inbox) and then sorting it on my desktop pc into the correct personal folder ...
